UPDATE: In our document search, we just found out why the FBI was involved in the Michael Jackson molestation case. According to one of the docs, the LAPD Sexually Exploited Child Unit contacted the FBI in 1993, asking the agency if it would be "interested in working a possible federal violation against Jackson concerning the transportation of a minor across state lines for immoral purposes."

The FBI was secretly involved in the child molestation case against Michael Jackson, according to documents just released by the agency.

In July, 2004, a memo was drafted stating that the Santa Barbara County District Attorney's investigation produced "collateral investigative issues, some of which potentially rise to the level of Federal Violations, in the New York and Miami Divisions as well as the Los Angeles Division." The memo does not elaborate on the nature of the alleged offenses.

According to the docs, FBI special agents from L.A., New York and Miami were assigned to assist Santa Barbara county prosecutors in their case against Jackson -- a case in which Jackson was found not guilty.

The memo says the special agents and prosecutors spent time discussing various strategies in the case.

There are also documents showing the FBI was involved in the 1993 molestation investigation. In one doc, there are notes which state Jackson was riding in a train with a boy whom Jackson identified as his cousin. The notes say, "He was very possessive of boy," and at night on the train a witness "heard questionable noises through wall."
